This allows follow-on trades such as construction of interior partitions, faade work, and MEP to start their work earlier. Because this form of concrete is cast in a controlled environment, these products can be more durable and long-lasting than other types of concrete. Prestressed concrete construction has the following disadvantages: High quality heavy duty dense concrete is required. Concrete is a mixture of coarse (stone or brick chips) and fine (generally sand and/or crushed stone) aggregates with a paste of binder material (usually Portland cement) and water.When cement is mixed with a small amount of water, it hydrates to form microscopic opaque crystal lattices encapsulating and locking the aggregate into a rigid shape. . Portland cement is the commonly used type of cement for production of concrete. Types Of Polymer Concrete: 1. These bridges need less quantity of steel, concrete and formwork. The followings are the disadvantages of prestressed concrete: It requires high-strength concrete and high-tensile-strength steel wires. 2) It requires high tensile steel, which is 2.5 to 3.5 times costlier than mild steel. The time, ranged for buildings and nonbuilding structures in contrast, concrete.
